Wired is reporting that Cornell University researchers genetically modified a human embryo in 2007, but have only recently been gaining publicity as their work is being reviewed. "The research raises a number of thorny ethical questions. Though adding a fluorescent protein was merely a proof-of-principle step, scientists say that modified embryos could be used to research human diseases. They say embryos wouldn't be allowed to develop for more than a few weeks, much less implanted in a woman and brought to term."

An embryo is the whole human, although just very young. In its natural state, it WILL grow, form a personality and wreck daddy's car in about 17 years.

I've noticed it also depends on whether or not the person arguing is the one that has to support it. Seems that people are more than willing to argue against abortion when they don't have to support the child in the end. I agree with the semi-serious argument that all anti-abortion advocates should have to sign up to adopt all the children that their cause prevents being aborted.
That flimsy argument aside, the US recognizes 90 days of development as to when an abortion can occur, so any embryo that is not developed past that point should be able to be terminated in the US without receiving any permission from a legal authority. The US does not define what methods are acceptable for creating embryos, both natural and artificial means are accepted. So whether or not an embryo is in a placenta or a petri dish should also be irrelevant. Since embryos can be frozen for years, it should be based on physical development, not length of time.

I think that point is often chosen because it's not arbitrary. It's a significant developmental event. Twelve hours before, three weeks later; those are arbitrary points. Your second example of an arbitrary point, when the baby is born, isn't arbitrary either. A true arbitrary point would be something like "after the first trimester."
There's a few other significant points in the development of a baby, such as first mental activity, first heartbeat, and so on. Those aren't arbitrary either. They may not be the correct basis to distinguish a human from a fetus, but they aren't purely subjective.

Lots of logic problems here.
Fertilization is the only logical point to draw a line ans say HERE is where a seperate entity begins. Sperm is just a part of you, the egg is just a part of her. When they meet something is created that isn't either of you. Consult a basic biology text is this isn't clear; The parts about immune system issues between the fetus and mother should be especially instructive.
Time of birth is unsuitable for a multitude of reasons. First off, a child a few days from delivery would have an almost 100% chance of independent survival with modern medical science. Happens all the time, some trauma forces an early delivery, etc. But the current legal regime, and your stated position, would allow the same baby who could equally be delivered and have an almost normal chance of a productive life to be aborted instead. Fairly major ethical problem.
Of course we (in the US) live in a Republic that clearly has birth as the legal definition of citizenship. Says so right in the Constituition. The legal problem can be fixed of course.
> I've noticed it also depends on whether or not the person arguing

This is a popular straw man argument. First off, once you conclude you are dealing with a child and not a tissue mass support is a given. After all you can't legally kill off a two week old by denying it basic life support. If you accept the child argument it is totally consistent. Besides, there are long waiting lists to adopt so the argument fails anyway.

It is getting harder and harder by the year to find a legal scholar who won't admit Roe v Wade wasn't one of the worst cases of legislation from the bench in the 20th Century. Depending on such a dubious 'ruling' isn't exactly an appeal to reason. Besides, medical science has advanced a lot since the 1970s and will only continue. Arbitrary 'viability' cutoffs are dangerous ground to stake out firm moral or even legal positions.

Invalid arguement (Score:4, Insightful)
First, you lump all religious people (hint: this is most of the planet) into the category of "people who cause genocide." Second, you offhandedly pronounce that, on the whole, the effects of religion are evil. Then, you conclude that religious viewpoints should not be heard. I say that you can't back up any of those statements.
It would be just as easy to out-of-hand dismiss Slashdot users (the only group I can knowingly lump you into) as incapable of reasonable political debate.
The fact is, this is an ethical question. It presumes that human life is valuable, and asks whether embryos qualify, and then asks how their interests balance against the other considerations.
The idea that human life IS valuable is just as much a belief as the idea that embryos do or don't qualify as humans. Whether you call that belief "religious" or not, it's still a belief.
I happen to believe that human life is valuable because we "are endowed by our Creator with certain unalienable rights." I make no argument about the faith of the Founding Fathers, but they did start with that premise. If you toss out the Creator, I assume you have some alternate rationale, but I don't think it's reasonable to say that any religious basis for valuing human life is irrelevant.

At this age they are not self aware. Basically they don't know they exist. I don't see the difference between studying an embryo of that age and studyng plants.
We are already using animals that are aware of their existance in labs. Apes can recognise themselves in front of a mirror and we are using them so I feel this is really not a big issue and we should let science go ahead.
Now I'm going to start a very heated debate. We know that babies start to be self aware around the age of 2 so if you really want to test my logic I'll tell you my opinion. We could logically use babies to make tests. Why this horrifies people is because they are attached to their own babies but since these newborns are not sentient yet, where is the harm in using "lab babies"? They would have to be grown in artificial wombs and all that to dehumanize them but logically it shouldn't be stopped.
I might be modded down for opening a can of worms but try to have fun with this ethical puzzle.

I am sick and tired of the word "embryo" (Score:5, Informative)
There are *2* stages of development before the blob of a few hundred cells is considered an "embryo". First, there's the formation of the zygote after fertilization, and then there's the formation of the blastocyst. The blastocyst is basically a hollow fluid filled sphere consisting of an outer layer of trophoblast cells which eventually become the placenta and an inner blob of cells called the embryoblast which eventually forms the embryo after the blastocyst phase.
When talking of "embryos", scientists are usually talking about the extracted embryoblast cells which are pluripotent stem cells. These cells are *NOT* viable and are just that : cells -- they're not going to grow into a baby, or an "embryo" for that matter. Even I would be upset if it were found out that the real embryo, after the start of cell differentiation, had been tampered with.
To conclude, stem cells are not embryos -- they're just a multiplying blob of undifferentiated pluripotent Human cells and as such, they should be put in the same class as pond scum, although pond scum is actually far more highly developed -- the aforementioned stem cells cannot survive outside of a Petri dish (unless they're implanted into another nutrient source, such as the Human body for purposes of healing)

Many would accuse you of dodging the issue with that definition. The problem is that to get those stem cells, a fertilized human egg is, at some point, stopped from developing farther. If life begins at conception, trying to tell people you only killed a blastocyst, not an embryo, isn't going to do much for you.

I would be against genetically modifying a viable human fetus, or even something that would normally develop into one. However, I wouldn't be against culturing human cells, and would love to hear that they're growing kidneys in a lab someday.
But when you're doing experiments on individual stem cells, it becomes hard to tell those two situations apart, and our common-sense notions of morality get befuddled. It's like an ethical version of quantum mechanics.

Clearly your anger has less to do with the pain of falling than with your deep-seated feeling that "it's wrong to harm others." You would not describe this as a preference.
Whatever we say about the source of morality, I think everyone feels that certain things are simply wrong. To deny this removes an important aspect of what it means to be human.
I know that someone will say that different cultures have different concepts of morality, but I don't buy it. There are different applications, yes; but no culture values cowardice and treason and murder. Some cultures defend their genocide and slavery by arguing that the victims aren't human, for example, but they do this because they must justify their actions against the standard that genocide and slavery are wrong. Our instinct to make excuses shows that we agree with the standard.

Not human because they, for example, believed and acted like they were a superior form of life and that all others were placed within their view for their own amusement?
